Hello, we are building an application for condition monitoring of machines. For this, I am trying to figure out the appropriate accelerometer with the following specs: (1) a frequency response of 1.5 to 2 kHz, (2) a high ODR, higher the better, (3) an analog anti-aliasing filter, and (4) a resolution of at least 14 bits. After looking at different accelerometers, I have zeroed-in on LSM303AH and ISM330DLC (we'll be utilizing only the acc sensor). Can you please suggest which among the two should be preferred over the other (for this particular application)? Or, if these are not the appropriate ones, could you please suggest other options.
